The present invention is a continuation-in-part of co-pending U.S. patent application Ser. No. 10/786,654 filed Feb. 25, 2004, which in turn claims priority on U.S. Provisional Application Ser. No. 60/458,598 filed Mar. 28, 2003, both of which are incorporated herein by reference.

The present invention pertains to the art of exercising equipment and more particularly to a portable unit which can be used by an individual to perform various exercises.

BACKGROUND OF THE INVENTION

Physical fitness of individuals has continued to become an important component of a person's health. Medical studies continue to show that an individual that exercises regularly can enhance his or her longevity and/or reduce incidents of heart disease, respiratory problems, diabetes, and/or other types of diseases. Individuals that are continuously on the road due to their jobs (e.g., salesmen, executives, truck drivers, airline pilots and flight attendants, etc.) are frequently away from home for extended periods of time, thus have difficulty in maintaining a daily exercise schedule. As such, it is not uncommon that such individuals do not regularly exercise, or begin an exercise program and soon thereafter give the program up due to the difficulty in maintaining the exercise program.

In view of the problems associated with maintaining an exercise program for individuals that frequently travel, there is a need for an exercise unit that is portable and which can be easily and conveniently used by an individual away from home to enable the individual to exercise while such individual is traveling.

SUMMARY OF THE INVENTION

The present invention is directed to a portable exerciser which addresses the needs of individuals that frequently travel. More particularly, the portable exerciser is designed to be made in a convenient form so that a traveler can easily pack such a device and transport such a device when traveling on the road. The portable exerciser can not only be used by individuals that frequently travel, but also for individuals that periodically travel for business, vacationers, and the like. Although the portable exerciser of the present invention is directed to a traveler, it will be appreciated that the portable exerciser can be used by other individuals (e.g., office workers, work-at-home workers, stay-at-home moms, etc.).

In one non-limiting aspect of the present invention, the portable exerciser is designed to allow individuals to exercise their upper and/or lower body areas. As such, the portable exerciser can be used as the principal exercising device for the individual, or be used as a-supplement for the individual in combination with other exercising devices and/or exercise routines (i.e. push-ups, sit-ups, crunches, stretching exercises, etc.).

In another and/or alternative non-limiting aspect of the present invention, the portable exerciser includes a mat formed of at least two primary components which are connected together. The two or more of the primary components can be connected together in a variety of ways such as, but not limited to, mechanical hinges, straps, rope, Velcro, flexible materials, etc. In one non-limiting embodiment of the invention, the mat can be formed of two primary components; however, this is not required.

DETAILED DESCRIPTION OF THE INVENTION

Referring now to the drawings wherein the showing is for the purpose of illustrating preferred embodiments of the invention only and not for the purpose of limiting the same, FIGS. 1-3 disclose one non-limiting portable exerciser in accordance with the invention. Referring new to FIG. 1, portable exerciser 10 includes a collapsible mat 12 formed of two primary components which are connected together, a first primary component or back mat 14 and a second primary component or bottom mat 16. These two primary components can be connected together in a variety of ways such as, but not limited to, mechanical hinges, straps, Velcro, flexible materials, etc. In the illustrated embodiment, one or more hinges 18 connects a bottom surface 22 of the first primary component 14 to a bottom surface 24 of the second primary component 16. The hinge is designed to maintain the two primary components together. The hinge can be a continuous hinge along the complete length or a portion of the length of the bottom surfaces of the two primary components, or can be formed of two or more spaced apart hinges. As can be appreciated, the two primary components can be permanently connected together or detachably connected together. The two primary components are designed to form the collapsible mat 12 and be oriented to allow an individual to place his or her head, back, and buttocks on the mat. As such, the two primary components 14, 16 of the mat provide comfort to the individual during the exercise routines when using the portable exerciser. The collapsibility of the two components 14, 16 of the mat 12 enables the portable exerciser 10 to be reduced in size for easy packing, carrying, and/or transporting. The size and shape of the two primary components 14, 16 is generally the same; however, this is not required.

As best illustrated in FIG. 3, each of the primary components is generally D-shaped; however, it can be appreciated that other shapes can be used. The D-shape for primary component 16 has two rounded comers so as to facilitate in the comfort of the legs of the user when using the portable exerciser, especially when placed in a seat or elevated position.

The width and depth of the each of the primary components is typically about 1-5 feet, and more typically about 1.5-3 feet; however, other dimensions can be used. The thickness of each of the primary components is typically about 0.5-4 includes, and more typically about 0.05-2.5 inches; however, other thicknesses can be used.

Referring now to FIG. 4, a cross-section of primary component 14 is shown. Primary component 14 includes a compressible material 18 and a generally rigid or less flexible material 20. The compressible material is typically positioned on the top side of the primary component. The compressible material is used to provide comfort to the user when positioned on the portable exerciser. The rigid material is used to provide rigidity and structural integrity to the primary component. Non-limiting examples of compressible materials include, but are not limited to, foam, rubber, gels, air pockets, blown polymers, and/or the like. Non-limiting examples of rigid materials include, but are not limited to, wood, metal, fiber materials, plastic, composite materials, etc. The compressible material is typically connected to the rigid material by, but not limited to, adhesives, rivets, nails, staples, thread, snaps, Velcro, tacks, etc. As can be appreciated, a primary component can be formed of a single material that is both compressible and provides the necessary rigidity of the primary component. Such materials can include, but are not limited to, rubber materials, etc. Primary component 14 can also include a durable top surface (not shown) that is designed to resist wear by the user during the use of the portable exerciser. Such materials can include, but are not limited to, vinyl, leather, nylon, Kevlar blends, rubber, and the like. As can be appreciated, primary components 14 and 16 can be formed and/or designed with the same or different materials. As can also be appreciated, many color schemes for the primary components of the mat, and/or textures of the components of the mat, can be used.

Referring now FIG. 2, the backside 30 of primary component 14 includes various components connected thereto. As can be appreciated, primary component 16 can also include various components connected thereto. The one or more components connected to the primary component 14 and/or primary component 16 can be permanently connected or detachably connected to the primary component. The backside of primary component 14 is shown to be a generally flat surface; however, this is not required.

As illustrated in FIG. 2, an adjustment mechanism 40 is connected to primary component 14. As can be appreciated, one or more components of the adjustment mechanism can be connected to primary component 16; however, this is not required. The adjustment mechanism is designed to enable primary components 14, 16 to be positioned in an angular relationship to one another. As illustrated in FIG. 2, adjustment mechanism 50 includes a first generally U-shaped support bar 42 and a second generally U-shaped bar support 44. As can be appreciated, the one or more support bars can have other shapes. Each of the support bars can be a solid non solid. The support bars are illustrated as having a generally circular cross-sectional shape; however, it can be appreciated that other shapes can be used (e.g., oval, polygonal, etc.). The support bars can be formed of a variety of materials such as, but not limited to, wood, plastic, metal, composite materials, fiber materials, etc.

Each of the support bars is illustrated as being rotatably mounted to the backside 30 of primary structure 14. The mounting of the one or more support bars in this fashion enables the support bars to be collapsed to facilitate in the storage of the portable exerciser and to also enable primary component 14 to be adjustably positioned relative to primary component 16. Many different arrangements can be used to rotatably secure the support bars to primary component 14. As illustrated in FIG. 2, mounting brackets 46 are used to rotatably secure the supports bars to the backside 30 of primary component 14. The mounting brackets are shown to be secured to the backside 30 of primary component 14 by screws 48; however, other connectors can be used (e.g., nail, rivet, bolt and nut, etc.). One or more of the support bars can be formed of two of more pieces (not shown) so as to enable the one or more support bars to be collapsed or otherwise reduced in size when the portable exerciser is positioned in a collapsed position; however, this is not required.

Support bar 42 is illustrated as having a greater width than support bar 44; however, this is not required. The greater width of support bar 42 is used to provide stability to the primary component 14 when primary component 14 is angularly positioned relative to primary component 16. The different shaped and sized bars also facilitates in the compactness that the support bars can be positioned relative to one another when the portable exerciser is to be stored.

As illustrated in FIG. 2, support bar 44 is rotatably mounted close to bottom surface 22 of primary component 14. As can be appreciated, support bar 44 can be mounted and/or secured to primary component 14 in other manners and/or be positioned in other locations on primary component 14. As can also be appreciated, a support bar could be mounted at or near bottom surface 24 of primary component 16 (not shown), slidably mounted on primary component 16 (not shown, or be telescopically received in primary component 16 (not shown). Support bar 44 is designed to have a sufficient length to provide stability to primary component 14 when angularly positioned relative to primary component 16, and to also have a sufficient length to enable support bars 44 and 42 to position primary component 14 and primary component 16 in the desired angular position relative to one another. Typically, the length of support bar 44 is about 40-150% of depth D of primary component 14, and more typically about 50-100% of depth D of primary component 14, and still more typically about 60-85% of depth D of primary component 14.

As illustrated in FIG. 2, support bar 42 is rotatably mounted near the mid-depth of primary component 14. As can be appreciated, support bar 42 can be mounted and/or secured to primary component 14 in other manners and/or be positioned in other locations on primary component 14. Typically, the length of support bar is less than support bar 44; however, this is not required. When the length of support bar 42 is less than support bar 44, support bar 42 is typically about 40-99% of the length of support bar 44, and more typically about 60-80% of the length of support bar 44.

As illustrated in FIG. 2, support bar 44 includes a plurality of spaced apart engagement members 60. The engagement members can have many forms (e.g., notches, grooves, C-shaped structures, pins, latches, clips, etc.). As illustrated in FIG. 2, the engagement members are in the form of three sets of notches that are designed to receive a top section 50 of support bar 42. The spaced notches enable top section 50 of support bar 42 to engage and be maintained on different regions of support bar 44 along the length of support bar 42. As such, primary component 14 of mat 12 can be selectively angularly adjusted and maintained relative to the primary component 16. As such, support 42 is adjustably engageable with support bar 44 such that primary component 14, when rotated or otherwise positioned relative to primary component 16, may be fixed at a predetermined angle relative to the primary component 16. As shown in FIG. 3, the angular relationship of primary components 14, 16 is about 180° when the two components are essentially in a flat position. As shown in FIGS. 1 and 2, primary components 14, 16 are oriented between 90°-180°. In this arrangement, primary component 16 is positioned essentially flat against a floor or other generally flat surface (e.g., car seat, surface of bed, chair seat, etc.) and primary component 14 is positioned in a non-perpendicular position to the floor or other generally flat surface. As illustrated in FIG. 2, there can be multiple position settings for the support bars 42, 44 to enable a user to orient the primary component 14, 16 angularly with respect to one another to obtain the desired position for an exercise and/or the desired comfort level during the use of the portable exerciser. As can be appreciated, many different mechanisms can be used to orient the two primary components from 0° to 360° with respect to one another.

As illustrated in FIGS. 1-3, two exercise components 70 are connected to each primary component 14, 16 of mat 12. As can be appreciated, different types of exercise components can be connected to one or more of the primary components. As can also be appreciated, more or less than two exercise components can be connected to one or more of the primary components. As illustrated in FIGS. 1-3, the exercise components are in the form of a handle 72 and stretchable strap 74 arrangement. Each of the exercise handles 72 are connected to a resilient stretchable strap such as, but not limited to rubber, elastic, or the like, which is designed to resist being stretched by a user during an exercise routine. Each of the two stretchable straps 74 include a clip 76 at one end and a clevis pin 78 at the other end. Clip 76 is used to secure handle 72 to the stretchable strip. The clip can be designed to enable the handle to be disconnected from the stretchable strap; however, this is not required. Clevis pin 78 includes at least one hole 80 as illustrated in FIG. 3 that is used to secure the clevis pin to pin bracket 90 that is secured to the backside of primary component 14 by screws 92. The clevis pin can be designed to be disconnected from the stretchable strap; however, this is not required. The pin bracket is designed to receive a portion of clevis pin 78 and be releasably locked to the pin bracket by inserting a clevis pin lock 94 into hole 80 in the clevis pin as illustrated in FIG. 2. As can be appreciated, many other arrangements can be used to releasably secure the stretchable strip or other type of exerciser component to primary component 14 and/or primary component 16. As can also be appreciated, the stretchable strip can be secured to other or additional regions on the primary component (e.g., side, front side, top , etc.). Although FIG. 1 illustrates the exercise handles and their respective stretchable straps being connected to both of the primary components of the mat, it can be appreciated that during a particular exercise routine, one or both handles can be connected to one primary component of the mat and only one or none of the handles and stretchable straps can be connected to the other primary component of the mat. As such, the portable exerciser can have increased flexibility in how it can be configured for particular exercises. As can also be appreciated, the one or both of the primary components can have various connection locations to secure one or more type of exercise components to one or both primary components so as to further increase flexibility in how the portable exerciser can be configured for particular exercises. As can also be appreciated, one or more of the exerciser components can be non-detachably connected to one or more of the primary components.

Referring again to FIG. 1, when an individual sits him or herself in the portable exerciser 10, the handles 72 and stretchable bands 74 that are attached to the portion where the individual sits can be used by the individual's legs to provide exercising routines to build up the legs and lower body, whereas the handles 72 and stretchable bands 74 that are connected to the mat to which the upper portion of the individual is laying against can be used to build up the arms and upper body of the individual. As can be appreciated, the degree of flexibility or the ease of stretching of the stretchable bands 74 can be adjusted by substituting one band for other types of bands. In one non-limiting arrangement, each handle 72 could be designed to be easily detached from a particular stretchable band and the handle can then be reattached to a different type of stretchable band having a different tension or resistance to extensibility. As such, a user could then select a particular tension for the stretchable band to obtain the desired degree of difficulty when using the portable exerciser during a particular exercise.

Although not shown in FIGS. 1-3, the portable exerciser can be packaged in a convenient holder so that it can be easily transported by a user. The holder can be designed to contain multiple sets of stretchable bands and/or other exercising accessories. In addition or alternatively, the portable exerciser could include one or more handles so that it can be easily transported by a user. In addition or alternatively, the mat of the portable exerciser can include one or more heating element, one or more massager components, and/or one or more magnets to enhance one or more functions of the portable exerciser.
